Description
7-0 Port AD1 reduced drive—Select reduced drive for Port AD1 outputs
RDR0AD1 This register configures the drive strength of Port AD1 output pins 15 through 8 as either full or reduced independent
of the function used on the pins. If a pin is used as input this bit has no effect.
1 Reduced drive selected (approx. 1/5 of the full drive strength).
0 Full drive strength enabled.
